Question

On a string of lights, for every 6 green lights, there are 4 white. If there are 30 green lights, how many white lights are there?

Answer 1

If there are 4 white lights for every 6 green lights, then there are 20 white lights for every 30 green lights.

6 * 5 = 30 green lights
4 * 5 = 20 white lights
